This is a discussion on dyno chart @ 19psi =) within the Comparison: WRX vs World forums, part of the Community - Meet other Enthusiasts category; Tuned by Robbie @ Epic Motorsport (epicparts.net)
Turned out about where I suspected.. going for 22 lbs of boost when ...

I'm guessing they still got room.. I should hit 350-360 21 psi on cobb software. Rob was hesitant to go farther with open source since ecu is kind of unpredictable. Also pushing limits of WRX engine/trans here so I don't want to run it much harder.

How is the ECU any less predictable with the open-source reflash rather than Cobb? Sounds to me like he just doesn't know Romraider very well. A reflash is a reflash - there should be no difference in "predictability"

put an ewg on it. the GS/Tial kit is only like $600, regardless of hp external is just a better way to go for engine life and for power. Not sure why your going with pistons, also be aware boost does a number on stock parts. I had an issue of the intercooler pipes blowing off the gaskets @ 19.. lol. Had to T bolt clamp them.

That's what I'm wondering. I haven't kept up with OSS on 08 or 09's, but this just doesn't sound right.

I'm going to get pistons because the stock pistons on the EJ25 have serious ring land issues, and I'd rather prepare myself for the boost than be sorry down the road and have to replace the block or sleeve it. Man, I didn't even think about the IC pipes...yeah those will probably have to be replaced, and probably the IC too. That is $$$.
